The distance of the bird from the ground will be given by:
tan θ=opposite/adjacent
θ=50°
opposite=h
adjacent=12 ft
plugging in the values in the formula we get:
tan 50=h/12
thus
h=12tan50
h=14.301 ft
=14.3 ft

Mathematics

10% of 60 is 6.

60 - 6 = $54 at a discount of 10%.

This price is discounted by 40%.

40% of 54 is $21.60.

The final price is $21.60 It's not equal to a 50% discount because half of 60 is 30, making the final price $30.

Hope this helps!
